 * PSI元素类,表示溢出处理注解的溢出策略参数部分

 * 示例:
 * ```cangjie
 * @OverflowThrowing[checked]  // checked是溢出策略参数
 * @OverflowWrapping[wrapping]  // wrapping是溢出策略参数
 * @OverflowSaturating[saturating]  // saturating是溢出策略参数
 * ```
 *
 * 此类用于封装溢出处理注解(@OverflowThrowing, @OverflowWrapping, @OverflowSaturating)
 * 中方括号内的溢出策略标识符。
 *
 * 支持的溢出策略包括:
 * - checked: 抛出异常(用于OverflowThrowing)
 * - wrapping: 环绕处理(用于OverflowWrapping)
 * - saturating: 饱和处理(用于OverflowSaturating)
